Coroutine-based solution for delayed and periodic work
/**
* Coroutine-based solution for delayed and periodic work. May fire once (if [interval] omitted)
* or periodically ([startDelay] defaults to [interval] in this case), replacing both
* `Observable.timer()` & `Observable.interval()` from RxJava.
*
* In contrast to RxJava, intervals are calculated since previous run completion; this is more
* convenient for potentially long work (prevents overlapping) and does not suffer from queueing
* multiple invocations in Doze mode on Android.
*
* Dispatcher is inherited from scope, may be overridden via [context] parameter.

Dumping heap of a Java process running in AWS ECS

Heap dumping a Java process running in AWS ECS

Note: this guide is designed for AWS ECS services, but starting from Step 4 is functionally equivalent to any Docker container on a Linux host.

Step 1. Look up ECS service

  1. Log into the AWS Console using the appropriate AWS account
  2. Navigate to AWS ECS service clusters (https://console.aws.amazon.com/ecs/home)
  3. Make sure you are in the correct region, if not, switch to the correct region (second drop-down menu in top right corner)
  4. Select the correct cluster (ex: https://console.aws.amazon.com/ecs/home?region=us-east-1#/clusters//services)
  5. In the Services tab, In the 'Filter in this page' text box, type the name of the service
